Referential Integrity is a feature provided by the RDBMS (Relational Database Management System), which prevents applications or users from entering incompatible data. Most RDBMS’s have different referential integrity that can be applied when you create relationship between two or more tables.
You can update the tables, having referential integrity applied, using the Microsoft Access append query. The append query adds records from the Access database table that you are using to another database table. The append queries are fine for adding data to various tables where the data is based upon the selection criteria.
However, append queries are good for appending the database records or tables, these are not always the most effective way of adding data to another database. Sometimes, when you try to append an Access database table, you might receive the following error message:
Microsoft Access can’t append all the records in the append query.
Microsoft Access set 0 field(s) to Null due to a type conversion failure, and it didn’t add record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations.
Do you want to run the action query anyway?
To ignore the error(s) and run the query, click Yes.

In such situations, when you try to export the data from the inaccessible database to a new database, you may get the following error message:
The Microsoft Jet Database Engine could not find the Object “. Make sure the object exists and that you spelled its name correctly.
This problem is the possible result of Access database corruption which could be due to application malfunction, improper system shutdown, virus attack and many alike. To work around the corruption problem, you can use Compact and Repair inbuilt Access database tool.
But in most of such situations, the Compact and Repair does not work and may show the following error message when you apply the same:
“Could not find field Description”
This is the worst case scenario which a computer user could face. If the corrupted database contains the business critical data then it becomes mandatory to repair and restore the database to make your data accessible.
The database repair is feasible with the help of third party applications known as access recovery software. Access recovery software are easy to use and fast access repair solutions which are applicable in most of the cases of Access recovery.
